AAHBS provides a cohesive national approach to FRDC-supported aquatic animal health R&D in Australia by providing leadership, direction and focus for health R&D and other related non-R&D activities. AAHS was renewed in 2012 based on national need, previous performance and strong stakeholder support. Key strengths include its strategic focus and the establishment of a network of aquatic animal health experts and research providers. An external review of AAHS was undertaken in 2015 and it found that the consensus among the major stakeholders was that AAHS provides an essential service for the major stakeholders. Thus, continuation of AAHS beyond 2016 on the basis of a shared financial commitment by stakeholders from industry and governments is highly desirable.

Australia’s aquatic animal sector is free from many diseases that occur overseas, providing us with a competitive advantage in both production and trade. While the number of aquatic animal species and the absolute number of aquatic animals being farmed in Australia is increasing annually, new diseases caused by emerging infectious agents (e.g. new yellow head virus genotypes, oyster oedema disease, ostreid herpesvirus, Bonamia exitiosa) continue to threaten the sustainability of significant enterprises, and the call on health services to support this expanding industry is growing.

In addition to aquaculture, aquatic animal health R&D is required for the other aquatic animal sectors, including wild-capture (c.f. Edwardsiella ictaluri in catfish), recreational (c.f. Perkinsus in oysters) and ornamental (c.f. gourami iridovirus), that share the aquatic environment. Thus health services need to be coordinated across all aquatic sectors to ensure synergy while avoiding duplication. FRDC, through AAHBS, plays a major role in addressing research needs and training in aquatic animal health. With its incumbent expertise and experience, AAHBS is able to direct these activities in the most pressing areas.

Viral diseases are among the most important of all health issues in aquaculture and fisheries. Their rapid and accurate recognition is central to the prevention of spread and the control of emerging diseases. Morphological diagnosis based on gross pathology, histopathology and electron microscopy remain vital in the diagnostic process, and are essential to complement accurate molecular aetiolgical diagnosis. Practitioners of morphological diagnosis are becoming scarce, and this application enables knowledge transfer from one of the world's foremost experts, Dr Teruo Miyazaki from Japan. This knowledge transfer requires a hand-on approach in a small group setting, using a multiheaded microscope with plenty of opportunity for discussion. for this reason a face-to-face visit is essential. Improving aquatic animal health diagnostic capacity is a priority for FRDC specifically to prevent and manage disease incursions, and to develop diagnostic procedures and techniques to rapidly detect and identify pathogens. This is also a priority for state jurisdictions.

In addition to viral diseases, Dr Miyazaki has career long expertise in general fish pathology, so his visit presents diverse opportunities for continuing education of Australian aquatic animal health diagnosticians.
